Product Description

 

Product Description

Seamless Tube require the precision of size tolerance ,which are mainly used in ships,marine platforms ,bullet train,aerospace equipment  and so on for the fine dense card sets connected instrument tube ,hydraulic brake tube, oil well control pipeline,chemical injection pipe and electric heating steam heating tube . 

Our company has introduced advanced high-speed precision multi-roll mill and bright annealing furnace .High-speed precision multi-roll machine can greatly improve the tube diameter and wall thickness tolerance.The seamless tube diameter tolerance our company produces is up to 0.3%D ,and the wall thickness tolerance we can produce is up to 3%S,which effectively solve the problem of size tolerance of connection of precision steel tubes and cutting sleeves.our company uses advanced bright annealing process by using a closed furnace under the protection of argon and nitrogen to make the surface of seamless tube not exposed to oxygen to produce oxide skin ,which can keep the inside and outside of seamless tube and the original surface of metal bright and clean.During the process of bright annealing ,the furnace temperature will be controlled accurately.The normal furnace temperature will be controlled at up and down 5ºC to make the steel tube  annealing evenly and fully insulated ,so that the seamless tubes will have better mechanical performance ,which can be bent and reaming treatment .

In order to ensure the quality of seamless pipes,our seamless factory--YONGSHANG owns automatic heat piercing production line,automatic temperature-controlled natural gas annealing furnace ,precision cold rolled line equipment ,each specification automatic straightener,automatic temperature-controlled cycle picking passivation equipment,semi-
Automatic cold-drawing production equipment and so on,and we also owns a full set inspection/testing equipment including Germany-imported direct-reading spectrometer, ultrasonic fault detector,eddy current flaw detector,hydrostatic test machine,universal testing machine,impact tester,endoscope etc.
